Best replacement for vscode.window.activeTextEditor?

[TylerLeonhardt]

Something that’s done in the PowerShell extension is:

                // v THIS
                const editor = vscode.window.activeTextEditor;
                // ^ THIS
                let selectionRange: vscode.Range;

                if (!editor.selection.isEmpty) {
                    selectionRange =
                        new vscode.Range(
                            editor.selection.start,
                            editor.selection.end);
                } else {
                    selectionRange = editor.document.lineAt(editor.selection.start.line).range;
                }

So that we can get the selected range or the range of the full line if nothing is highlighted. We take this selection and run it in the terminal below.

Is there any good replacement API for this in coc?

Use await workspace.document to get current document.
Use workspace.getSelectedRange to get selected range.

[TylerLeonhardt]

@chemzqm I might be using it wrong… but I get [coc.nvim] Command error: document.getPosition is not a function.

My code:

const doc = await workspace.document;
const range = await workspace.getSelectedRange('v', doc.textDocument);

[chemzqm]

You should pass result of visualmode function as mode argument

[TylerLeonhardt]

Where can I find that function?

[TylerLeonhardt]

I found this:

const editMode = (await workspace.nvim.mode).mode

but it doesn’t seem to work right:

const doc = await workspace.document;
const editMode = (await workspace.nvim.mode).mode
const range = await workspace.getSelectedRange(editMode, doc.textDocument);

// OUTPUT: [coc.nvim] Mode 'n' is not supported

This is odd because I was in visual mode when I ran my command that triggers this code (F8 which runs an editor command whos code I’m looking to simplify 😅)

[chemzqm]

Checkout :h visualmode() and https://github.com/neoclide/coc.nvim/blob/master/src/handler/index.ts#L694

[chemzqm]

The command can take argumenst, you can pass visualmode() by :CocAction('runCommand', 'id', visualmode())

[TylerLeonhardt]

Ok so that gives me this at the bottom:

Then I hit ENTER and get:

[coc.nvim] error: TypeError: Cannot read property 'client' of undefined
    at Object.ActionsList.addAction [as execute] (/Users/tyler/.local/share/nvim/plugged/coc.nvim/build/index.js:69304:33)
    at ListManager.doItemAction (/Users/tyler/.local/share/nvim/plugged/coc.nvim/build/index.js:66877:50)
    at process._tickCallback (internal/process/next_tick.js:68:7)

What I ran:

:CocAction("runCommand", "powershell.evaluateSelection", visualmode())

My code:

let doEval = async function(mode: string) {
            let document = await workspace.document
            if (!document || document.filetype !== 'ps1') {
                return
            }
            
            const doc = await workspace.document;
            const range = await workspace.getSelectedRange(mode, doc.textDocument);

            client.sendRequest(EvaluateRequestType, {
                expression: content,
            });

            await proc.scrollToBottom()
        }

let cmdEvalSelection = commands.registerCommand("powershell.evaluateSelection", async (mode) => doEval(mode));

Don't know how you invoke action list, it's better to build coc.nvim from source code so you can debug it by Chrome, instead of ask me https://github.com/neoclide/coc.nvim/wiki/Debug-coc.nvim
